How to create a new security group and assignments of rigths?

In our current "Cisco Unified CM Administration System version: 7.0.1.11000-2" installation, we are a couple of administrators using the same user account to logon to the "https://10.10.x.x/ccmadmin/showHome.do" homepage.

Where can I create a new user group and assign the appropriate rights to the group, and add users to the group? Or is it another approach that I need to follow instead of the way that security rights a made in a Microsoft Active Directory?

Is there any place that I can read or view examples on how the setup can be done? I would like to have it in the way that everyone has their personal user account and use this to logon the administration-web page instead of an account that everyone uses.
